Not once a year and neither every day as a rule. You will get rewarded for the coins that are in your wallet, as there are many wallets with coins, everybody will get their share when your weight (days without reward, time online, qty of coins) is becoming "heavy". For you to receive the stake you need to be online...to increase your weight you don't..... so it can happen that you stay offline for a week and when you come online you wallet starts to receive coins after a few seconds.
I didn't ask the question, but helped me out non the less.
Thank you so much!
maybe because BTC dow - from 3k to 2.2 k now
